This invention relates to condensers.

The object of the invention is to provide a condenser particularlyadapted for condensing the vapors of a solvent used for extracting cafgfeine from coiee and for other similar purposes.

'With this and other objects in view which `will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction. as hereinafterdescribed and claimed, it being undery stood that changes in the detailsof the inven tion and in the combination of parts may be made within thescope of the claim without de parting :trom the spirit of the invention.

,In the accompanying drawings forming part of this specification,

Figure l is a perspective view of the improved .condenser, part of thetank of which is broken away to show the elements Within.

Figure 2 is a View o one ci' the six condensing chambers shown in Figureif Figure 3 is a detailed view in vertical section on the line 3--3 orFigure 2, showing a portion of the condensation chambers.

Figure 4 is a detailed plan View oi' the overow from the cooling tank.

Generally described, the condenser of this in.- vention includes acooling tank i into the lower portion of one end oi which, cold water isintroduced through a pipe 2.

The Water is jetted vertically upward from the water inlet 2 through aseries of jets 3. The ca pacity of the pipe 2 is sufficient to feed alioi the Arranged in the cooling tank i are six condensation chambers i-twhich extend lengthwise ci the tank as indicated in Figure l and arespaced away from each other.

The arrangement of jets 3 relatively to the water inlet 2 is such thattwo of said jets are on opposite sides of each of the condensationchambers l, as clearly shown in Figure 1, and said jets as indicated inFigure l are set slightly inward from the ends of the condensationchambers so that the cold water is jetted upward on both sides of eachof the condensation chambers. y

The cooling water in the tank continuously ows through the pipe 2, jets3 and out of the tank at the opposite end through the overow pipe 5which maintains constant level of cooling water in the tank.

By locating the cold water inlet 2 at one end of the tank and theoverflow 5 at the other end of the tank and by directing the jets 3upwardly, the cold water rst passes upwardly in the tank i and thenflows towards the bottom and the overow pipe 5 constantly drains ci! thewarmer strata of water at the top.

The tank l preferably is made of wood supported on beams and when theappara- G tus is not in use the water may be drained from the tank ithrough the drain pipe 1. The condensation t. i-l are suitably supportedupon sleepers or cross-bars B t as shown in Figure 1. I

The solvent whidh has bn employed :for leaching or extracting thecodeine from the coffee or other duid to be acted upon, is vaporized andenters the apparatus through an enlarged vapor header Si, which extendstransversely across 1d the top of the tank i and is connected with allof the condensation chambers M by means of the down pipes it-i@, each ciwhich extends through a flared inlet portion ii into one of thecondensation ch w t.

The condensate passes out from the bottom of each, oi the condensationchambers t through a ared outlet i2, into an outlet it which extendsinto a main outlet it, which extends transversely oi the tank i. Each cithe outlet pipes i3 and the inlet 'pipes i@ are in tvvo sectionssuitably joined together by ange joints i5, which are staggered asindicated in Figure 1, so as not to interfere with each other and yetpermit ready access for assembling or disassembling the tanks.'

As shown in Figures i and 3, each of the con densation chambers hasextended transversely across it a series of stainless steel rivets ortubes it, which serve to reinorce and strengthen the condensationchambers.

Each of the condensation chambers, as shown in Figure l, is providedwith alternating bade partitions which are marked from the top down--ward as i'i, it, mdd, 2i, 22. A

it will be observed that the partitions il, it and 2i are placedimmediately above the rivets i6 so as to m reinforced thereby. I t willbe further observed that each'of the partitions numbered ii, it and 2iextend from the center of the tank in opposite directions, anddownwardly sloping to a point spaced away from the ends of the t.

It will also be observed that the partitions i8, 2&3 and 22 areconnected with the ends of the tank and extend inwardly and downwardlyto a point spaced away from the center of the tank.

It will further be observed that when the vapor enters each of thecondensation chambers 4 at the point ii, itpasses through a restrictedspace dened by partition I'l and the top of the tank l,

and that the gas then expands out into a wider space produced by thedown incline of the partition I1 at each end.

It will also be observed that any liquid which condenses on thepartition i1 tends to drip from the opposite ends thereof in the form ofa cascade through which the gas man at the restricted point formedv bythe partitions Il and I8. and the gas then down at the center throughthe opening in the partition it, and then repeats the same course in dto am.' tions I9, 2t, 2i and 28. n

It will be further noted, from Figure 1 that the bottom d a of eachcondensation tank is sloped on the incline tow the outlet pipes i3 so asto permit the condensate to ofw into the outlet i4.

IWhat is claimed as new is:

In a condenser, a tank provided with an overflow outlet for coolingwater and containing a. plurality of closely and parallelly spacedhollow, hat, relatively thin, vertically disposed vapor condensing unitsarranged in parallel and located below said overow outlet, vapor inletmeans for each of said condensing units, condensate outlet means foreach of said condensing units, cooling water inlet means in said tankdisposed adjacent the bottom of said tank and having inlet jets on eachside of each of said condensing units, which jets are adapted to-jet theincoming water onto the sides of said condensing units'.
